Specification of Letters Patent.

Patented Apr. 1, I913.

Application filed August 10, 191.1. Serial No. 643,325.

To all whom it may concern:

Be it known that I, Josnrn A. Warm, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Lay-Boys, of which the following is a specification.

My invention relates to certain improvements in means ling the position of the feeding mechanism in relation to the pile of paper of a layboy used in piling paper as it comes from a cutting machine.

The invention also relates to certain details of construction, which will be fully described hereafter, reference being had to the accompanying drawing, in which:

While my invention is particularly adapted as a lay-boy used in connection with mechanical means for feeding paper to a pile, it will be understood that the invention can be used for piling paper by hand, or by any.

suitable apparatus, as the inain object of the invention is to provide an apparatus In which the top of the pile will be on sub-' stantially the same level, the pile receding as the paper is added to it This is particularly' of advantage in piling by hand, as the operator plac' g the paper on the pile does not have to alter his position.

Figure 1, is a side view of my improved lay-boy; showing it in position in respect to the cutters which sever the continuous web of paper, forming sheets which are properly piled; Fig. 2, is an endview; Fig. 3, is an enlarged side view partly in section, showing the details of the pneumatic mechanism for controlling the position of the pile of sheets in respect to' the feeding mechanism; Fig. 4, is a sectional view on the line 4-4, Fig. 3; Fig. '5, is a sectional view, drawn to an enlarged scale, on the line 5--5, Fig. 2; Fig. 6, is an enlarged view of part of Fig. 2, and Fig. 7, is a'view illustrating a modification of the invention.

A is the frame of the lay-boy. I

B is the platform upon which the paper as is piled. This platform is suspended from shafts B on which are chain drums b. Chains I) extend from the drums and are at tached to eyes 6 through whichpass bars B. These bars extend under the platform B and properly support the-platform in position. As the paper is piled upon the platform, the platform is automatically lowered for automatically controlby mechanism which will be described here after and which turns the shafts B. The shafts are supported in suitable bearings secured to the upper portion A of the frame A.-

E is a truck having wheels e-e and this truck passes underthe platform B. When the pile of paper has reached the height desired, the platform Bis lowered on to'the' projectingribs e of the truck and transferred to any point desired.

C-C are the feed rollers, which carry the web of paper from the paper making machine or from a reel, as desired.

0 c are the cutters, which cut the web of paper intosheets of the desired length. The length of the sheet may be varied by increasing or diminishing the speed of the cutter c.

D and F are endless belts between which the sheets of paper are gripped and conveyed to the pile. The belt D passes around drums d (IV-d while the. belt F passes around drums f-f'. The drums (Z and f are; mounted on adjustable bearings so as to increase orvdiminish the tension of the belts. The paper, as it is cut, is gripped between the two belts D and F and is fed forward on to the pile, as indicated at w; the paper coming in contact with .a stop 9 on a depending frame G and held laterally in position by guards g and h. I

z' is 'a' jogger which is moved toward and from the pile of paper being, in the present instance, mounted on a rock shaft I, driven in any suitable manner. There is a setof guards g and h on each side of the machine and there is also a jogger on each side. Thus, the paper is evenly piled upon the platformB. i

In order to always maintain the discharge and mountedbetween the disks is a diaphragm m of any suitable material. The

fecting, the diaphragm, but as soon as the papercommencesto close the port, as in Fig. 4, then the'supply of air to the pump is, less than the capacity. of the pump and the suction will draw the diaphragm down and as this diaphragmv controls the feed medhanism it will allow said feed mechanism to o erate to lower the platform and the pile o Ipaper, and willinsure the openingof the port it so as to give the suction pump more air, after which the feed mech-- anism will stop until the opening is again contracted. In the present instance, the dia-' phragm m is .connected to a rod m, WlllCll bears against the underside of the weighted arm I: of a two-armed leverK pivoted at k and adjustably mounted on a rod'm are nuts m which bear against the under side,

of the arm is. By turning these nuts the movement .of the lever K can beregulated.

On the rod m are thumb nuts m and beao tween the thumb nuts and the upper casing M is a spring m and by adjusting the thumb nuts on the rods, the tension of the spring can be regulated so as to place more or less resistance on the suction pump.

On the arm k of the lever K is a pawl 12, which engages the teeth of a ratchet wheel PL, secured to the shaft :P and on this shaft is a sprocket wheel P and passing around this sprocket wheel is a chain P. The chain 40 also passes around a sprocket wheel Ron a shaft B. On the shaft R are two worms 8, 7 one at each side of the machine, which mesh with the worm wheels 8 on the shafts B so that as the'shaft P is turned motion will be imparted to the' shafts B causing the platform B to be lowered. In order to impart feeding motion to the pawl p, I provide an eccentric t on a shaft T. T is an eccentric strap, which passes around the eccentric t and is connected at its outer .end to an arm 72* on the pawl 12. When the diaphragm is in its normal position, the pawl is in' its forward position and must return in order to feed the ratchet 56 wheel P forward.' It will be seen that the i eccentric t has only a limited movement and will not actuate the pawl until "it is moved 1 o by the drawing down of the diaphragm M andirelea'sing the weighted bell crank lever. 60 As soon as the bellcrank lever is released, then the eccentric will cause the awl to turn the shaft P through the medium 0 the ratchet wheel any number of teeth desired, according to the particular throw of the ec- 6 centric. The shaft T is operated fromthe carried by arms Q, adjustably mounted on main power shaft W through belting leadingto a pulley on'the shaftT, which, in turn, is carried to the shaft T. In the pres ent instance, the suction pump N is. also driven from the shaft W.

In order to adjust the stop 9 to conform to the length of the sheets to be piled, I make the'suspended frame G adjustableand in the present instance I provide two racks G, which are suitably mounted on the overhangingframe A. The teeth of these racks are on the under sideand meshing with the teeth are pinions g which are mounted on a shaft Gr carried by the frame G and on the inner end of each shaft G is a hand wheelv g by which-the'shaft is turned so that'onturning the shaft, the frame G is moved toward and from" the feeding mechanism and is held'in the position to which it is adjusted, so as to insurethe proper piling 5 of the sheets of paper.

The frames J supporting the joggers and guards h are laterallyadjustable so as to conform to the width of the paper and in the present instance there .is a bar J on which the frame J slides and this bar has teeth j on its upper surface and meshing with-the teeth is a pinion j on a shaft J? having a. handle f. .On turning thehandle the frames'J can be adjusted toward and from each other.- The jogging motion is imparted to each shaft I by a cam 'v on a shaft V. V This cam engages the arm i on the shaft 5 and causes the shaft to rock. In the present instance, the arm 71 has two rollers i one located on each. side of the cam '2), but other connections'may be used without departing from the essential. features of the inventgon. The shaft V is driven by the rollers On the shaft V is an eccentric '0', having a strap which is connected to a rod 0 which, in turn, is connected to a rock arm w having a series of joggers w which act to force the sheet of paper-after it is freed from the feed belts D and .1 toward the stop 9 and alternating with these joggers are guides to which hold the sheets of the pile of paper in the proper position, as shown in Fig. 5.

In order to feed the sheet of paper properly to the pile, I preferably arrange means for slightly turning up the sides of the sheets of paper so as to stiffen it as it is released from the control of the feed belts and thus the paper will pass evenly to the stop and will lie properly upon the pile. In

order to accomplish this, I provide rollers 9', which project into the path of the aper at the edge of each sheet and these r0 lers are a cross bar Q.

Directlyback of eachroller 1s a gui le V which is formed as shown and 'slightlybends the edge of the sheet so that r the sheet, when projected from the feeding mechanism, will lie evenly on the pile.

While the feed belts D and F may, in some instances be single belts, I prefer to make them, as shown clearly in Figs. 2 and 6;

there being, in this instance, a series of roller 9 are located in such a position as to properly curl the edges of the paper for the purpose described above. In some instances the rollers and guides may be so located as to bend the sheet at the center instead of at the edges producing good results. Instead of vertically moving the platform as the height of paper increases I may locate the platform in a fixed position and raise the.

arm carrying the feed mechanism, as clearly shown in Fig. 7, in which B is the platform and A is a frame mounted on the standard A and this frame carries the feed belts F and D.

N is the suction pump.

M is the diaphragm casing having a diaphragm connected to the lever K and the ratchet wheel is on a shaft P aroundwhich passes a chain a connected to the sliding frame A Carried by the frame A is a guide a. for the paper and in this guide is a port a communicating'with the suction pump through a tube (1 ,50 that as the pile of paper increases and the port a is partially closed, the suction pump will operate the diaphragm which, in .turn, will cause the feed mechanism to raise the frame This is the same principle as is illustrated in the construction shown in Figs. 1 and 2, only the platform is moved instead of the feeding mechanism. i

The operation of the mechanism illustrated in Figs.,1 and 2 is as follows ':--The platform B is suspended in position, in front of the feed mechanism and the'web of paper is fed through the mechanism and is cut into proper lengths to form the sheets desired. The side guides, end stops, and joggers have all been adjusted. The severed sheet is fed by the two sets of feed belts D and F and as the pile of pa erwon the platform increases in height it Wlll partially close the port 71.; causing the suction pump to draw the diaphragm down, thus throwing the pawl into operative position. The eccentric'will then cause the pawl to turn the ratchet wheel which will lower the platform B so that the top of the pile of paper will be sufficiently clear of the port 71. to allow suflicient air to pass through the pdrt to supply the suction pump. Thus it will be seen that the mechanism automatically controls the position of the platform .and the pile of paper, always insuring the proper relation between the pile and the feeding mechanism. This the sheet of paper is properly laid upon thepile. I

other platform being placed in preferably slightly arch 'the sheet'by the use of the roller 9 and guide V so as to slightly stiffen the sheet in order that it may be properly placed upon the pile. The

guides and oggers are readily adjusted so as to accommodate sheets of different sizes.

After the pile of paper .on' the platform B has reached the proper height, then the platform is lowered on to the truck E and the paper conveyed to any point desired; an? position to receiveanother pile of paper. Itwill be understood that where the web of paper is cut into longitudinal strips and these strips severed so as to form separatepiles that the height of the piles-is controlled by the pile in close proximity to the port communicat-. ing with the suction pump. I

. I claim 1. The combination in a lay boy, of a platform; means for feeding sheets of paper' to the platform; means for verticallymovmg one of said elements with respect to the other; suction mechanism, for actuating said-means, having an inlet opening above the platform and in close proximity to one side of the pile of pa er; the paper acting as. a'val-ve to regula the amount of air passing to the suction device so that when the pile increases in height the means for moving one of said elements, with respect to the other, will be actuated.

2 The combination in a lay boy, of a platform; means for feeding sheets of paper to the platform; automatic pneumatic means for governing the position of the top of the pile of paper in respect to the feeding mechanism; a suction pipe connected to the pneumatic means and located in close proximity to the pile of paper so that as the pile increases .in height the opening in the pipe is gradually closed; the pneumatic means.being actuated to lower the height of the pile of paper so asto expose more of the opening in the suction pipe.

3.-T'he combination in alay boy, of a platform; feeding mechanism for feeding sheets of paper to be piled on to the platform; a suction pump; mechanism for changing the relative osition of the platform and feeding mec anism; with means for controlling the changing mechanism actuated through the medium of the suction pump; and an 'air passage for supplying air to the suction pump located in the path of the paper so that as the pile of pa er in creases it will close, or partly close, t e passage communicating with the suction pump, thus causing the pump to release the changing mechanism.
